Always love to see companies using horror in advertising. This is a spooky video campaign for Sony Ericsson called St Mary's Ghost. The video in itself is not very scary, the St Mary'S hospital ghost looks more like a vampire to me, but viewers can enter their own or their friend's mobile number, triggering a scary call from the ghost - spooky, just in time for halloween. Click on the link to visit stmarysghost.com to view the full video and to send a call from St Mary's Ghost to your friends, or check out the abriged version below.
